Microbial Nanocellulose Printed Circuit Boards for Medical Sensing

Apr 01, 2021 | Jonathan D. Yuen, Lisa C. Shriver-Lake, Scott A. Walper, Daniel Zabetakis, Joyce C. Breger and David A. Stenger

We demonstrate the viability of using ultra-thin sheets of microbially grown nanocellulose to build functional medical sensors. Microbially grown nanocellulose is an interesting alternative to plastics, as it is hydrophilic, biocompatible, porous, and hydrogen bonding, thereby allowing the potential development of new application routes. Exploiting...

Study on Real-Time Test Script in Automated Test Equipment

Mar 24, 2021 | Chongwu Jiang, Bin Liu, Yongfeng Yin, Chang Liu

In this article we propose a generic test script for real=time embedded software system testing, which has been applied to ATE (Automated Test Equipment). After a summary of the theory about embedded software automated test based on test script, the design philosophy and implementation details are described. We have chosen an ATE and integrated python interpreter into it....

Test Solution for Heatsinks in Power Electronics Applications

Mar 24, 2021 | Davide Piumatti, Stefano Borlo, Matteo Vincenzo Quitadamo, Matteo Sonza Reorda , Eric Giacomo Armando and Franco Fiori

Power electronics technology is widely used in several areas, such as in the railways, automotive, electric vehicles, and renewable energy sectors. Some of these applications are safety critical, e.g., in the automotive domain. The heat produced by power devices must be efficiently dissipated to allow them to work within their operational thermal limits. Moreover ......

Analyzing the Impact of X-ray Tomography on the Reliability of Integrated Circuits

Mar 18, 2021 | Halit Dogan, Md Mahbub Alam, Navid Asadizanjani, Sina Shahbazmohamadi, Domenic Forte and Mark Tehranipoor

X-ray tomography is a promising technique that can provide micron level, internal structure, and three dimensional (3D) information of an integrated circuit (IC) component without the need for serial sectioning or decapsulation. This is especially useful for counterfeit IC detection as demonstrated by recent work. Although the components remain physically intact during tomography, the effect of radiation on the electrical functionality is not yet fully investigated. In this paper we analyze the impact of X-ray tomography on the reliability of ICs with different fabrication technologies....

Latent short circuit failure in high-rel PCBs caused by lack of cleanliness of PCB processes and base materials

Mar 10, 2021 | Stan Heltzel

Latent short circuit failures have been observed during testing of Printed Circuit Boards (PCB) for power distribution of spacecraft of the European Space Agency. Root cause analysis indicates that foreign fibers may have contaminated the PCB laminate. These fibers can provide a pathway for electromigration if they bridge the clearance between nets of different potential in the presence of humidity attracted by the hygroscopic laminate resin. PCB manufacturers report poor yield caused by contamination embedded in laminate. Inspections show ......

MPPE/SEBS Composites with Low Dielectric Loss for High-Frequency Copper Clad Laminates Applications

Mar 04, 2021 | Jianming Guo, Hao Wang, Caixia Zhang, Qilong Zhang, and Hui Yang

Copper clad laminates (CCLs) with low dissipation factor (Df) are urgently needed in the fields of high-frequency communications devices. A novel resin matrix of modified poly (2,6-dimethyl-1,4- phenylene ether) (MPPE) and styrene-ethylene/butylene-styrene (SEBS) was employed in the fabrication of high-frequency copper clad laminates (CCLs). The composites were reinforced by E-glass fabrics, which were modified with phenyltriethoxysilane (PhTES). The composite laminates obtained exhibited impressive dielectric loss of 0.0027 at 10 GHz when the weight ratio of MPPE to SEBS was 5:1....

Progressive Failure Analysis of Laminates with Embedded Wrinkle Defects Based on an Elastoplastic Damage Model

Mar 04, 2021 | Zhi Hua Ning, Guan Liang Huo, Ren Huai Liu, Wei Lin Wu and Jia Ming Xie

Out-of-plane wrinkling has a significant influence on the mechanical performance of composite laminates. Numerical simulations were conducted to investigate the progressive failure behavior of fiber-reinforced composite laminates with out-of-plane wrinkle defects subjected to axial compression. To describe the material degradation, a three-dimensional elastoplastic damage model with four damage modes (i.e., fiber tensile failure, matrix failure, fiber kinking/splitting, and delamination) was developed based on the LaRC05 criterion. To improve the computational efficiency in searching for the fracture angle in the matrix failure analysis, a high-efficiency and robust modified algorithm that combines the golden section search method with an inverse interpolation based on an existing study is proposed....
